Transcoding not working

[diverman]

Hi, I have set up transcoding as the following:
Port: 8002
Encoder: 1
Auto set frame rate: yes
Resolution: 480p

Then tried the mobile icon in OpenWebif - it has oppened the VLC - but not showing any content.
I checked the underlying URL:

root@vuduo4k:~# ./test-stream.sh
--2020-12-07 21:46:55-- http://vuduo4k:8002/1:0:1F:10C:2111:20CB:EEEE0000:0:0:0:

It has downloaded only few bytes and exited. While normal streaming on port 8001 works - it runs until I kill it:

Any ideas?
